I had the privilege tonight to speak at the Dallas .NET User Group.  While December
meetings are normally lightly attended, we had a good crowd who was very engaged on
the subject matter.  The talk reviewed XML namespaces, XPath syntax, and closed
with a review of the XmlReader object in the .NET Framework.

The slides and
code samples can be found here.

I appreciate everyone giving me some of their time and I hope you learned something.
